JAMES F. MCELROY, OF ALBANY, NE\V YORK, ASSIGNOR TO THE CONSOLL DATED CAR-HEATING COMPANY, OF SAME PLACE.

ELECTRIC HEATER.

SPECIFICATION forming part of Letters Patent No. 610,999, dated September 20, 1898.

Application filed March 1 8, 1 8 9 5.

To all whom it may concern.-

Be it known that I, JAMES F. MOELROY, a citizen of the United States, residing in the city and county ofAlbany, State of New York, have invented a new and useful Improvement in Electric Heaters, of which the following is a specification.

My invention relates to electric radiators; and its object is to provide an electric heater peculiarly adapted for use in a street-railway car, which maybe placed under the seat and allow air to circulate between the body of the car and said seat and after being warmed in said heater to pass into the car through perforations provided therefor.

I attain this object by means of the mechanism illustrated in the accompanying drawings, in which- Figure l is a front elevation. Fig. 2 is a plan view of the upper edge of the front piece 13. Fig. 3 is a cross-section along the lines 1 1 on Fig. 1. Fig. 4 is a longitudinal sec tion along the lines 23-2 on Fig. 3. Fig. 5 is a longitudinal section along the lines 3 3 on Fig. 4.

Similar letters refer to similar parts throughout the several views.

A A represent the riser of a seat in a streetcar, said seat being spaced sufficiently far from the body of the car to permit air to pass down between the two in the direction as indicated by the arrows in Fig. 3. The riser is cut away at a a for the purpose of inserting the perforated portion 0 of the metallic front piece 13 of the heater. The upper edge of the front piece B is provided with flanges E and F, adapted to be arranged in the position shown in the cross-section in Fig. 3 in such a manner that the flange F shall rest upon and the flange E support one end of the curved metallic plate G, held in position by means of the bolt or screw 6 or in any suitable manner. The curved plate G forms the top and back of the heater and is secured by means of the stove-bolts g or in any suitable manner to the lugs L on the side pieces II and is provided with suitable openings J J, through which the electric wires may pass. The side pieces II II have at their lower extremity a foot K K. The bottom of the heater is open. Thus a circulation of air is provided for be- Serial No. 542,225- (No model.)

tween the seat and the body of the car downward to the bottom of the heater, then upward in contact with the resistance through the heater and out through the perforated portion 0 in the front piece B.

The side pieces H H are provided with seats L L, upon which the hangers M M rest. To these hangers are secured the ends of the spindle N, which carries the insulating-core 0, upon which the resistance-wires P are coiled. The insulating-plate S, usually of porcelain, is placed between the hangers M and the core. The nut T is placed on the end of the spindle, and into this nut the bolt U,passin g through the side pieces II, engages, which holds the core in position. I also arrange suitable contact-screws V V for connecting up the heater. I usually place a nonconducting substance 0 around the top and back of the heater and a portion of the front, except that part which is provided with perforations.

The construction and arrangement of the heater as herein described enables it to be placed under a car-seat and be entirely protected at the bottom from the accumulation of dirt,sn ow, and other deleterious substances and forms a very tasty and compact heater, and being preferably constructed of metal and lined with a non-conducting substance radiation is prevented except through the perforated portion G.

Vhat I claim as my invention, and desire to secure by Letters Patent, is- V 1. An electric heater consisting of a casing provided with a perforated portion adapted to fit in an aperture of the riser of a car-seat and having a recessed lower portion adapted to fit behind said riser and below the aperture therein, flanges adapted to secure the front edge of said perforated plate, a resistance placed within said heater, a casing inclosing said resistance at the top and back thereof, bracket-supports adapted to sustain said casing and perforated plate upon the floor of the car, with a car-seat riser entirely closed except for theapertures in which said perforated plate is placed and a car-body having a seat arranged with passages between said seat and the outer wall of the car,- substantially as described.

2. An electric heater consisting of acasing provided with a metal front piece, the upper portion of which is perforated and projects through a perforation in the riser of the carseat, a rabbeted portion extending behind and below said riser, a suitable support with openings therein to permit air to enter from below, a non-conductive lining at the back and top of said casing, aresistance placed therein,

10 a car-body provided with a seat, a riser placed beneath said seat and entirely closed except where said perforated plate is inserted, said seat arranged to provide for an air-passage between the back of the seat and the outer wall of the car, substantially as described.
